The Museum of Lost Objects traces the histories of 10 antiquities or cultural sites that have been destroyed or looted in Iraq and Syria.

This is the oldest and smallest object in the series: a tiny Sumerian cylinder seal depicting a harvest festival. It was carved in 2,600 BC and was part of the collection of ancient cylinder seals which disappeared when the Iraq Museum in Baghdad was looted during the 2003 invasion of Iraq. We tell the story of this seal and the pillaging of the country's most important museum.

This episode was first broadcast on 11 March, 2016.
